Therib unay be cast in such a form as largely to answer 'the purposes of the ring 7,

an a' lat ring may be cast in the cylinder to take the place of` the rib 6 and the ring 7. I npFig. Iillustrate-how the rib 6 may be omitted and lts place be taken by the ring 7.

It is not thought essential that'there should .easy provislo'nffor 'expansion and contrac- `'.f. -ftion. prirneobject of rib 6 is to provide 2o; -unnecessary material in the cylinder.
